Awesome thank you! yes #23 was the bushing i was talking about. I tried uploading a photo but the 500k limit is a bit to work around, i need to find an program where you can size a picture by kb size and not just dimensions. O man am I in a pickle.....the drop brackets we ordered from someone that was referred to me on a separate forum ended up sending ones with the bolt holes completely backwards. They sent them a week later and without the bushing im asking about (i specifically asked if it was included and was assured it was). its been a nightmare dealing with them and it seems the broader Suzuki community (you aside, your freakin awesome and forgiving) seems less willing to help with the overall mishap of the issue and more about keeping the seller in a good reputation. i might just press out the old rubber portions on the cast iron drop brackets that were on it already. It looks as though they are not welded but pressed in? they look identical to the ones pictures in your schematic so im not sure if they are stock or aftermarket? Im going to give it a try and arbor press them out.... if id doesnt work im not out anything as i need to return the bogus brackets back to the individual that has caused so much headache. wanted to give you an update... Thank you so much for being the best source of information on these vehicles. On a side note i have an interview at a fabrication shop here in socal tomorrow. I hope i get it, i enjoy working on things like this. I also hope you feel i am worthy and capable of it. I will keep you up to date on the progress of the kick as its now in limbo for another week until the drop brackets are fixed or new ones show up.

glad you brought the picture in. I still have the #17 bracket, it was the #23 bushings i wanted replaced. The other two brackets, # 12 and 13, are fine, but the bushings in both (#15) are shot. it looks from your schematic that they are removable and not one piece with either #12 or 13. I bought brackets from a private seller not knowing #15 was removable so i figured the entire bracket was bad. i just need to replace part #15 as the rubber is old and shot. i will source parts for a bit and see what i can come up with

Hey kick wanted to get back to you. I was able to source the #15 bushings online as a direct replacement for the Suzuki part number.
The part number is Febest SZAB-010 and is a quarter of the price as the Suzuki part.
They also carry the same rubber bushing #23 and that Part number is Febest SZAB-007 and is a direct replacement as well but about the same price as from Suzuki.
I had the new #15 bushings pressed into the old brackets and everything went back together great.
I figured out you were originally right when you mentioned the locking hubs being a culprit in the clunk.
After replacing the bushings the clunk was still there so i noticed the cv axles have a little movement and that the clucking might be coming from the manual locking hubs we switched over to.
The funny thing is the hubs work and lock fine. I tested the 4 wheel drive system extensively this weekend with much success.
I will swap back over to the auto locking hubs and see if there is any difference.
